- Summary
- `Cookie` HTTP header isn't stripped on cross-origin redirects
- Details
-
urllib3 is a user-friendly HTTP client library for Python. urllib3 doesn't treat the
CookieHTTP header special or provide any helpers for managing cookies over HTTP, that is the responsibility of the user. However, it is possible for a user to specify aCookieheader and unknowingly leak information via HTTP redirects to a different origin if that user doesn't disable redirects explicitly. This issue has been patched in urllib3 version 1.26.17 or 2.0.5. - References
